Specifically, if you look at the top most character on the scenery side, the inner part of the circular shaped character has comparatively more space than the Y #22s (photos below). The bottom left of that loop area is much narrower, too. Also, if you look at the bottom character closest to the tower, my example is nowhere as close to the tower as the Y #22 examples. They are closer to the widest part of the tower, whereas mine is a bit north of its lateral position.

Is this just a different die (i.e. a thinner variation of the thin type; mines definitely not the thick type)? It seems strange that it's this huge of a difference, especially since there are different die types that were assigned their own Y #s. Of course, I would have just looked at the pattern example if there was one, but I couldn't find any. The strike also seems to be a little sharper.

I took a look at most of those and haven't come across one that matches yet.

Mine may just be a variety within the thin characters type, but so far it's different from the rest of the ones I've seen. I believe that the pattern ones are all proof strikes, if I'm not mistaken. The devices seem to contrast well with the fields on mine.

And, do you have an example image of the Pn9? Krause via NGC says that it's the same design, and notes Y22a as a reference, which is the gold version of the same design. Mine matches more closely with the Pn9 example shown by Krause than Y22.1 or Y22.2.
